On the excedance number of colored permutation groups
Eli Bagno, David Garber
We generalize the results of Ksavrelof and Zeng about the multidistribution of the excedance number of with some natural parameters to the colored permutation group and to th…
Colored-Descent Representations of Complex Reflection Groups G(r,p,n)
Eli Bagno, Riccardo Biagioli
We study the complex reflection groups G(r,p,n). By considering these groups as subgroups of the wreath products Z_r wr S_n, and by using Clifford theory, we define combinatorial p…
Sign balance for finite groups of Lie type
Yona Cherniavsky, Eli Bagno
A product formula for the parity generating function of the number of 1's in invertible matrices over Z_2 is given. The computation is based on algebraic tools such as the Bruhat d…
Permutation representations on invertible matrices
Yona Cherniavsky, Eli Bagno
We discuss permutation representations which are obtained by the natural action of on some special sets of invertible matrices, defined by simple combinatorial att…
